Detailed Description

Get information about what IDL features the IDL compiler has, similarly to the "version" standard header in C++.

In C++ it can be used like this if you want to be compatible with older versions of TAO:

#include "tao/orbconf.h" #if defined TAO_HAS_IDL_FEATURES && TAO_HAS_IDL_FEATURES // Use this macro if you are using something that's not the max possible // version.

define TAO_IDL_IDL_VERSION 0x30000

include "tao/idl_features.h"

if defined TAO_IDL_HAS_FEATURE && TAO_IDL_HAS_FEATURE

define USE_FEATURE

endif

#endif

In IDL it can be used like this if you want to be compatible with older versions of TAO:

#if defined __TAO_IDL_FEATURES

include __TAO_IDL_FEATURES

if defined TAO_IDL_HAS_FEATURE && TAO_IDL_HAS_FEATURE

define USE_FEATURE

endif

#endif

Note that support for annotations and anonymous types in IDL4 predate this file, so they are a potential special case depending on what ACE/TAO is being used.
